Ah, yes. I have gotten quite nasty about doing things inside observers, 
including making changes and then wanting to do have the change visible 
for more work in the observer. Since changes get deferred this gets 
hairy fast (esp. since I discovered that there is a double deferral! The 
deferred thing gets dispatched and since it is a setf (perhaps buggily, 
I have not thought it thru) immediately goes to the end of the queue). 
This is normally benign but with what I was doing it got nuts fast.

We may need a Cells5 soon. (Thomas forked and called it C4, I better 
skip 4).
